The present investigation is aimed at developing a multidisciplinary framework for the analysis of LAMP process. Since adhesion of the substrates depends on the thermal field developing during the process, a FE model was adopted to estimate the temperature field. Thus, experimental tests of LAMP were conducted on AISI 304 stainless steel and polycarbonate sheets to determine how the laser beam power and scanning speed affect the strength and the morphology of the joints. Finally, the local strength of the joint was related to the temperature field to build a strength-temperature function that enables the estimation of the overall strength of the joint. Although the study is still under development stage, early tests cases confirmed the effectiveness of the developed framework.

Abstract
The present investigation is aimed at developing a multidisciplinary framework for the analysis of LAMP process. Since adhesion of the substrates depends on the thermal field developing during the process, a FE model was adopted to estimate the temperature field. Thus, experimental tests of LAMP were conducted on AISI 304 stainless steel and polycarbonate sheets to determine how the laser beam power and scanning speed affect the strength and the morphology of the joints. Finally, the local strength of the joint was related to the temperature field to build a strength-temperature function that enables the estimation of the overall strength of the joint. Although the study is still under development stage, early tests cases confirmed the effectiveness of the developed framework.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
